SQL BIND
SQL BIND links a Q parameter to a table column. The SQL commands
"Fetch," "Update" and "Insert" evaluate this binding (assignment)
during data transfer between the result set and the NC program.
An SQL BIND command without a table or column name cancels
the link. The link is terminated at the end of the NC program or
subprogram, if not before.
You can program any number of bindings. Read and
write processes only take into account the columns
that were entered in the "Select" command.
SQL BIND... must be programmed
"Update" or "Insert" commands are programmed.
You can program a "Select" command without a
preceding "Bind" command.
If in the "Select" command you include columns
for which no link has been programmed, an error
occurs during read/write processes (program
interrupt).
Parameter no. for result: Q parameter that is
linked (assigned) to the table column
Database: column name: Enter the table name and
column description – separated by . a
table name: synonym or path and file name of this
table. The synonym is entered directly – path and
file name are entered in single speech marks
